Property checking extension

For a while I had posted a property checking extension for I7, intended to make sure that all objects and rooms in the game at least had some description defined. This turned out to be buggy because of the way the standard rules handle room descriptions, so I took it down for a time until I got around to figuring out what was wrong with it.

I have now solved this, so version 2 is up in the usual place. Apologies for the inconvenience/delay/etc.
